How to create custom cron job in magento

Magento default have a cron.php file located in the root directory. To set a cron in magento you have to create your own module first, and in the config.xml you have to declare the method which will fired and the time. Below is a dump of a etc/config.xml file of a custom cron module

<?xml version="1.0"?>

<config>

<modules>

<Wl_Cronset>

<version>0.1.0</version>

</Wl_Cronset>

</modules>

<crontab>

<jobs>

<Wl_Cronset>

<schedule>

<cron_expr>01 00 * * *</cron_expr>

</schedule>

<run>

<model>cronset/expired::productExpired</model>

</run>

</Wl_Cronset>

</jobs>

</crontab>

<global>

<models>

<cronset>

<class>Wl_Cronset_Model</class>

</cronset>

</models>

</global>

</config>



As per mentioned in this xml your cron will be fired every day @ night 00:01 min

Now you have to write your own functionality in your module Model file, Here my model file name is Expired and the function which will trigger is productExpired().

<?php

class Wl_Cronset_Model_Expired extends Mage_Core_Model_Abstract

{

public function productExpired()

{

// Your code goes here

}

}

?>



Now login to your server to call the magento root cron.php and set to be fired in every minute.
